I removed the 80GB hard drive from a dell inspiron tower and installed it into another computer system. every time i try to install windows , it stops during the part of installation where it says copying files to windows installation folders, when it gets to about 60% it says that the windows xp image copied to the hard drive is invalid and that there is a problem with windows xp installation disk. I returned the first three copies back to the store and finally decided that there wasn't a problem with the disk. So I then started with a process of elimination checking each possible scenario but everything checked out to be in working condition (CD-RW, RAM, VIDEO CARD, CPU, NETWORK ADAPTER) So then using fdisk i deleted the current partitions, created a new partition and then reformatted the drive but yet again I tried to install windows and it gave me the same stupid error after about 60% of the first part of the install. SO could it be that dell formatted this hard drive so that it cant boot/reformat/install into a non dell system? Any help to resolve this issue is greatly appreciated as i have already put more than 72 hours of time in trying to get this machine running for my cousin and her kids! Thanks in Advance!!!
